It is tracked in bug #1895643, which also includes the original and further discussion. This decision was discussed and then approved by the Ubuntu Technical Board on. Users of Ubuntu 20.04 not wishing to update beyond Thunderbird 68.x may instruct apt to hold or pin the package, but this is not recommended as the package will no longer receive security updates. We believe that in practice this will only affect a tiny proportion of users, if any. This extension has not been ported to Thunderbird 78 by upstream.

This extension is deprecated upstream and doesn’t function with Thunderbird 78. The enigmail package will be updated to a version of the plugin that guides users through switching to the native Thunderbird PGP implementation. They will need to switch to Thunderbird 78’s integrated PGP solution. Users may face disruption to their workflows due to changes between Thunderbird 68 and 78.Įnigmail users will face disruption, since Enigmail has been deprecated in Thunderbird 78. It makes sense to do this carefully, using the usual Ubuntu SRU process to maximise QA. It has therefore become necessary to move to Thunderbird 78.x. We don’t expect it to be practical to backport security fixes to Focal indefinitely. Thunderbird 68 is no longer supported by upstream. We’ve decided to update Thunderbird in Ubuntu 20.04 from 68.x to 78.x.
